I've recently started getting this message more and more frequently on my Echo Dot. Nothing has been changed on my network and none of the other devices connected to the same router have any problems. I've tried the obvious things like rebooting the router and restarting the Dot, but these only seem to cure it for a few days. Does anybody have any suggestions?
BTW, by frequently I mean two or three times a day, whereas they were hardly happened at all in the preceding months.
That was what was confusing me - removing the password is not the same as forgetting the network. When you attempt to reconnect, the settings previously used, apart from the password, will still be there. What is needed is a command to remove all the settings for that network.
